I UNITED I STATES PATENT QFFICEQ FRANK BA'RNEY, OF BLOOMINGTON, ILLINOISIMPROVEMENT IN CULTIVATO RS.

Specification forming part of Letters Patent No. 43,470, dated July 12,1864.

To all whom it may concern:

Be it known that I, FRANK BARNES, of Bloomington, in the county ofMcLean and State of Illinois, have invented a new and ImprovedUultivator; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being bad to theaccompanying drawings,forming apart of this specification, in which-Figuie 1 represents a longitudinal vertical section of my invention.Fig. 2 is a plan or top view of the same.

Similar letters of reference in both views indicate corresponding parts.

This invention consists in the application of a hand-lever, incombination with a triple crankshaft and with the hinged standards ofthe front and rear plows, in such a manner that by the action of saidlever the front shares can be moved laterally, and at the same timebythe combined action of the lever and crankshaft the front and rearshares can be raised from the ground simultaneously at any moment. 7

To enable those skilled in the art to make and use myinvention, I willproceed to describe it. t

A represents a frame, made of wood or any other suitable material, andsupported by two wheels, 13, which have their hearings on the ends ofthe stationary axle O. A draftpole, D, serves to draw the cultivatorthrough the field, and the frame A is elevated to such a height abovethe ground that it passes over the growing plants, partly by the largesize of the wheels and partly by curving the ends of the axle Gdownward. The frame A is composed of fourlmore or less) longitudinalbars, a a, and a similar number of cross-bars, b b, and the longitudinalbars a a form the bearings for the gudgeons c of the standards E, towhich the rear plows, F, are secured, and for the forked swivel-bracketsc, which sustain the standards Eof the front plows, F. The standards Eof the rear plows are secured to their gudgeons a, so that they swing upand down in a vertical plane, but are not capable to move in a lateraldirection independent of the frame A; but the front standards, E, are

secured to the forked brackets c by means of pivots d in such a mannerthat they swing in a vertical and in a lateral direction, and to preventthem from moving one independent of the other they are connected bybrakes e, secured to the same by means of pivots, so that they do notinterfere with their lateral motion.

G is a crank-shaft, which has its hearings in suitable boxes attached tothe longitudinal bars a of the frame A. The ends of this shaft formcranks f, which connect by chains and rods 9 with the rear standards, E,and two arms, f, which are rigidly secured to the same, connect bychains and. rods 9 with the front standards, E. Another arm,h, whichextends upward from the crankshaft G, connects by a rod, 73, with ahand-lever, H, which has its fulcrum on a pivot, j, in a swivel bracket,7c, inserted into one of the longitudinal bars, a.

The lower end of this lever is connected to one of the front standards,E, by means of a staple, l, or in any other suitable manner, andits topend is in convenient position to be operated from the drivers seat.

By depressing the hand-lever H in the direction of the arrow marked nearit in Fig. 1 all the plows are raised out of the ground simultaneously,and by moving the upper end of the lever in a lateral direction alateral motion can be imparted to the front plows in either direction,and said plows can thus be accommodated to the sinnosities of the rows.

This plow is very simple in its construction. It is easily operated, andall its parts are so arranged that they are not liable to get out ofrepair.

' What I claim as new, and desire to secure by Letters Patent, is-

The hand-lever H, with its swivel-fulcrum 7c, in connection with thecrank shaft G, hinged 'rear standards,E, and swivel front standards,

E, all constructed and operating in. the manner and forthe purposesubstantiallyas herein specified.
